Top 10 Best Kotlin Android Apps Development Companies

[Total: 0    Average: 0/5]

Kotlin was introduced by a Russian team at JetBrains. It understood the pain developers face in the day-to-day development workflow and with Kotlin it has attempted to address those. Kotlin takes a pragmatic approach by not including features such as having its own build system or package manager because open source tools such as Gradle and Maven already handle this well. Having its own build system would have broken projects that already use Gradle and Maven.

In Kotlin the java frameworks have not been re-implemented although it would have been easy to do that as the developers wanted it to be compatible with the JDK collection interfaces without breaking any existing project implementations. Both Kotlin and Java generate the same byte code.

The Null Pointer Exceptions have been removed from Kotlin which are one of the most common reasons for the crashed in the applications. With Kotlin, you needn’t worry about NPEs because null safety is baked into Kotlin’s type system. It is so nice to catch NPEs at compile time instead of crashing apps at run-time.

One of the amazing feature that the Kotlin plugin brings to the Android Studio is that you just give it a Java file and with one click it will convert it into an equivalent Kotlin file. Kotlin code is not verbose like Java, it is more crisp, concise and reduces a lot of much of the boilerplate code that developers must write everyday.

Kotlin is a language which is compatible with Java which is being used since a long period of time for Android development. It can be used with the popular libraries and tools that are written in Java. There is more security in Kotlin in terms of nullability and immutability which aligns to make android apps healthy and performant by default. The creators of Kotlin managed to bypass the weak points of Java, this allowed them to make Kotlin code incredibly laconic and expressive.
